Fermi Liquid Near a Quantum Critical Point

We investigate the approach to the quantum critical point of a Pomeranchuk instability from the symmetric, disordered side of the phase diagram. In the low-temperature limit, a Fermi liquid description of the metal is possible and becomes exact for T → 0. We discuss in detail which features of the approach to quantum criticality can be captured within Fermi liquid theory and which are outside of its scope.
